How to Choose the Right Furnace Replacement for Your Home

How to Choose the Right Furnace Replacement for Your Home

Many people underestimate the importance of having a reliable furnace in their home until it suddenly stops working when they need it most. This situation often leads to the question of how to choose the right furnace replacement for your home.

Consulting with a professional HVAC technician is paramount, but gaining insight into the key factors to consider when selecting a furnace replacement can empower homeowners to make the right choice.

Key Takeaways

  • Most furnaces are designed to last 15-20 years maximum. After this point it’s best to consider replacing them.
  • Signs that your furnace is ready to be replaced are the furnace’s age, rising energy bills, frequency of repairs, and inconsistening heating throughout the building.
  • Factors to consider when replacing a furnace include, energy efficiency, the size of your home, warranty and brand reliability, and the furnace’s noise level.
  • To get the most out of your furnace, you should have it serviced at least twice a year and work with a reliable HVAC specialist to ensure it stays in working order all year long.

What are the Signs That a Furnace Replacement Might Be Needed?

Recognizing the signs that your furnace may need replacing is crucial for maintaining a comfortable and efficient home. Here are some key indicators to look out for:

Furnace Age

Are you aware that furnaces usually have a lifespan of 15 to 20 years? If your furnace is nearing or has surpassed this age, it’s recommended to consider replacing it. Older furnaces consume more energy and are prone to breakdowns, which could result in significant expenses.

Rising Energy Bills

Are your energy bills rising despite no significant changes in your usage? Your furnace’s efficiency may be waning. As furnaces age, they consume more energy to deliver the same heat. This uptick in energy consumption can lead to higher utility costs, suggesting it might be time for a replacement.

Frequent Repairs Needed

If your furnace needs frequent repairs, replacing it could be more cost-effective. Regular breakdowns lead to expensive repair bills and disrupt your comfort and peace of mind. If repairing your furnace is getting close to the cost of buying a new one, it’s time to consider replacing it.

Inconsistent Heating

Are some rooms in your home always too hot and others too cold? This could be a symptom of an aging furnace. Over time, furnaces can lose their ability to distribute heat evenly throughout your home. Inconsistent temperatures indicate a deteriorating system and might require a furnace replacement.

Factors to Consider When Choosing a Furnace Replacement for Your Home

It’s essential to carefully choose the furnace replacement for your home as it dramatically impacts your home’s comfort, energy efficiency, and heating costs. To make an informed decision, you should consider several essential factors.

Energy Efficiency

When choosing a furnace, energy efficiency should be at the forefront of your considerations. This aspect is generally measured using the Annual Fuel Utilization Efficiency (AFUE) rating. A higher AFUE rating means that the furnace can convert a significant percentage of the fuel it uses into heat, increasing its effectiveness and reducing energy bills.

Investing in high-efficiency furnaces may come with a slightly higher price tag initially, but their long-term energy savings make them a smart and cost-effective option. Always seek out appliances with the ENERGY STAR label to ensure the highest efficiency level, indicating that they meet or surpass federal efficiency standards.

Size of Your Home

The size of your home plays a crucial role in determining the appropriate furnace size you need. A furnace that is too small won’t have the capacity to adequately heat your home during the coldest months, leading to discomfort.

Conversely, a furnace that is too large can lead to unnecessary energy consumption, resulting in higher energy costs. It’s not just about square footage; other factors, such as the number of rooms, insulation levels, windows, and the home’s orientation, can influence the heating requirements.

A professional HVAC technician can conduct a load calculation to determine the correct furnace size for your home.


A comprehensive warranty can provide peace of mind and protect your investment if a malfunction or breakdown occurs. Warranties vary significantly among manufacturers. Some cover only parts, while others cover both parts and labor. They also differ in length, with some extending up to a decade or more. Be sure to read the warranty terms carefully, understand what is and isn’t covered, and consider the length of coverage when comparing different models.

Noise Level

If you value a quiet home environment, the noise level of your furnace is another critical factor to consider. Some furnaces operate more quietly due to advanced design features such as insulated cabinets, sealed combustion, or variable-speed motors. 

The noise level of a furnace is usually indicated by its decibel (dB) rating – the lower the dB rating, the quieter the furnace. Remember, a quieter furnace can create a more peaceful and comfortable home.

Local Climate

To choose the right furnace for your home, it’s essential to consider your region’s climate. If you experience harsh winters, a high-efficiency furnace can effectively and efficiently keep your home warm. However, a standard-efficiency furnace may be more cost-effective if your winters are mild.

What Types of Furnaces Can You Choose From?

There are different types of furnaces for heating your home. Knowing their advantages and disadvantages can help you choose the best one. Below are some common furnace types to consider:

Gas Furnaces

One of the most popular furnaces is the gas furnace, which is efficient and cost-effective. It heats up by burning natural gas to warm a set of heat exchangers. Then, a fan blows air across these exchangers to spread heat throughout your house. 

Although a gas furnace could be more expensive than other types to install, they are cheaper to operate because natural gas is relatively low-cost.

Oil Furnaces

Oil furnaces are frequently used where natural gas is not easily accessible. They work by burning oil to create heat. Although less efficient than gas furnaces, they can generate significant warmth. They may be a suitable alternative if you have a reliable source of heating oil.

Electric Furnaces

Electric furnaces use electricity to heat elements made of conductive materials. When the thermostat calls for heat, these elements switch on and warm the air circulating through your system. 

Electric furnaces are generally less expensive than gas or oil and are quieter and more durable. However, they can be more costly to operate due to the high cost of electricity in some areas.

Heat Pump Furnaces

Heat pumps aren’t technically furnaces, but they serve a similar function. Instead of generating heat, they extract heat from the outside air or ground and move it into your home. Heat pumps can be incredibly efficient and heat and cool your home. They work best in moderate climates, as their efficiency can drop in freezing weather.

High-Efficiency Furnaces

High-efficiency furnaces, sometimes called condensing furnaces, use advanced technology to maximize energy usage. They extract heat from the exhaust gases that would otherwise be vented out of your home, resulting in significantly lower energy consumption. While they come with a higher upfront cost, they can result in substantial savings over time due to lower energy bills.

Maintenance Tips for Your New Furnace

Proper maintenance is critical to ensuring the longevity and efficiency of your new furnace. Regular upkeep not only enhances performance but also helps prevent unexpected breakdowns. Here are some essential tips for maintaining your new furnace:

1. Schedule Regular Inspections

Ensure regular professional HVAC inspections to maintain optimal performance and prevent future malfunctions. Prioritize scheduling inspections before the heating season begins to address potential issues. 

A qualified technician will thoroughly examine all components, clean the system, and highlight any concerns that could result in expensive repairs or replacements. Adopt this proactive approach to safeguard your HVAC system and avoid unnecessary expenses.

2. Change Filters Regularly

One of the simplest yet most effective things you can do is regularly change or clean your furnace filters. Dust, dirt, and other particles can clog the filter over time, restricting airflow and causing the furnace to work harder, leading to increased energy consumption and possible damage. 

Most experts recommend changing disposable filters or cleaning reusable ones every one to three months during the heating season.

3. Keep Vents Clear

Ensure all vents in your home are clear of obstructions like furniture, curtains, or rugs. Blocked ducts can restrict airflow, causing your furnace to work harder to distribute heat evenly throughout your home. Regularly check your vents and keep them open and unblocked for optimal performance.

4. Clean the Furnace Area

It’s essential to keep the area around your furnace clean and debris-free. Dust can enter the furnace and cause it to work less efficiently. Additionally, flammable items near your furnace can pose a safety risk. Regularly vacuum or dust the area around your furnace to keep it clean.

5. Check the Thermostat

Your thermostat plays a crucial role in controlling your furnace. Ensure it’s functioning correctly and is set to an optimal temperature. If you have an older thermostat, consider upgrading to a programmable or smart thermostat for better control and energy savings.


6. Listen for Unusual Noises

While furnaces aren’t silent, unusual noises like banging, squealing, or rattling could indicate a problem. These sounds could indicate various issues, including loose parts, ignition problems, or airflow reductions. If you hear strange noises, it’s best to call a professional for a thorough inspection.

7. Monitor Energy Bills

A sudden increase in energy bills could indicate that your furnace isn’t working as efficiently as it should. If your furnace consumes more energy without a noticeable change in weather or your comfort level, it might be time to call a professional to check it out.
